HORACE B. PHILLIPS, or FAIRMONT, NORTH CAROLINA.

STILL.

To all whom 25 may concern Be it known that I, HORACE B'. PHILLIPS, a citizen of the United States, and a resident of Fairmont, in the county of Robeson and State of North Carolina, have made certain new and useful Improvements in Stills, of which the following is a specification.

My invention relates to improvements in stills, more especially those stills used for the production of turpentine, and it consists in the combinations, constructions, and arrangements herein described and claimed.

An object of my invention is to provide a device in which pine wood containing turpentine may be treated without any danger of overheating the wood.

A further object of my invent-ion is to provide a device Of a portable nature which may be readily set up in one ksection and moved to another.

A further Object of my invention is to provide a device having a furnace so constructed and located that much of the heat which would be otherwise wasted is saved.

A further obj ect of my invention is to provide a device in which the wood may be more readily led into and discharged from stills of the Ordinary type.

Other objects and advantages will appear in the following specification and the novel features of the device will be particularly pointed out in the appended claims.

My invention is illustrated in the accompanying drawings forming part of this specification in which- Figure 1 is a front view of the still, Fig. 2 is an enlarged sectional view, Fig. 3 is a section along the line 3-3 of Fig. 2, Fig. 4 is a section along the line 4 4 of Fig. 2, and Fig. 5 is a diagrammatical view showing the oil pipe connections.

In carrying out my invent-ion I provide a base 1 of rectangular box-like shape. This may be carried by a foundation 2 of any suitable construction. Mounted upon the base is a series of coils of pipe 3. As will be seen from Fig. 2, these coils are arranged vertically and adjacent coils are connected by short connections 3k. The spaces between the adjacent rows of vertical coils are designed to be filled with the wood 4 in the manner shown in Fig. 1.

Arranged to fit over the base portion 1 is a cover portion 5. This cover portion may be raised or lowered in any suitable manner such as by power devices (not shown) atv Specification of Letters Patent.

tached to the cables 6. The cover portion 5 bears the furnace. The latter consists of a casing 6 provided with grate bars 7, a door 8 in the wall of the top portion 5, and a chimney or stack 9. On the inside of the furnace preferably along the walls and top thereof are arranged coils of pipe 10. The two ends of the pipe coils 10 extend through the wall of the cover portion 5 terminating on the outside thereof as shown at 1()X and 10y respectively in Fig. 3. The ends 3X and 3.y of the coils 3 extend through the base member and terminate on the outside thereof. The' terminal portions 3X and 10x are connected by means of a'pipe 11. The termi.- nal 10y is connected by a pipe 12 to a pump 13, and the latter is connected to the pipe yFrom the foregoing description of the various parts of the device the operat-ion thereof may be readily understood. The apparatus is set up as shown and the furnace is filled with combustible material. The pipes 3 and 10 are designed to be filled with the oil or other suitable liquid. The heat from the furnace will cause the oil to become heated and it may then be pumped through pipes 3 and 10 by means of the pump 13. The coils 3 form not only heating members, but also racks for supporting the wood. The circulation of the oil p-rovides a heating medium which is sufficient to drive Off the t-urpentine which may be led out through the pipe 15 to a condenser (not shown). As the turpentine distils the tarry matter gathers in the bottom of the base 1 and may be drained oiiI at the cock 16.

l/Vhen the process is iinished the connecting pipes 10, 12 and 13 may be unscrewed and taken OH and the cover may be lifted from the base by any suitable power means. The wood may then be removed directly from the racks formed by the coils 3 and the charge may be placed in. The cover may the-n be lowered and the pipes 11, 12 and 14 may again be secured in place and the Operation repeated.

lty will be seen from the above construction that very little heat is wasted in the process. As fast as the oil is heated it is pumped out of the interior of the furnace into the heating co-il 3. The furnace being on the inside of the device utilizes any heat which might escape from the walls of the furnace were the latter Outside of the casing formed by the base 1 and the top 5. The pump may be run by any suitable motor and is designed to run at sucli speed as to per` tion, a furnace carried by said cover, and L means for heating the coils from the furnace.

2. l'n a still, a-base portion comprising a rectangular box, ay series of heating coils spaced apart to provide racks for the material to be treated, a cover for said baseportion, a furnace carried by said cover, means for heating the coils from the furnace, said means comprising a series of coils within the furnace, and connections between the coils of the furnace and the rack coils.

3. In a still, a base portion, a series of coils carried thereby, said coils being spaced apart to provide room for the material to be treated, a cover for said base portion, and a furnace carried by said cover on the inside thereof.

Lovese 4. In a still, a base portion, a series of coils carried thereby, said coils being spaced apart to provide room for the material to be treated, a cover for said base portion, a furnace carried by said cover on the inside thereof, means fo-r carrying of the products of distillation, and means connected with said base portion for draining the latter o the liquid products of distillation.

5. InY a still, a rectangular box-like base portion, a series of rows of vertically extending coils, said rows being spaced apart to form raclsrfor the material to be treated, a box-like cover arranged to surmount said base portion, a furnace carried Within said cover, pipes disposed within the interior of said furnace, said coils and said pipes being arranged to receive a circulating fluid, connectionsA between the pipes and said coils, and a pump for circulating the fluid in said pipes and said coils.
